Discrepancies between type-approval and real-world fuel consumption and CO2 values in 2001-2011 European passenger cars

In order to limit the negative effects of climate change and to reduce dependency on oil imports, the European Union (EU) needs to reduce its GHG emissions by 80-95% below 1990 levels by 2050. A...
